My All 2020 Mathematics A to Z: Big-O and Little-O Notation


Mr Wu, author of the Singapore Maths Tuition blog, asked me to explain a technical term today. I thought that would be a fun, quick essay. I don’t learn very fast, do I? A note on style. I make reference here to “Big-O” and “Little-O”, capitalizing and hyphenating them. This is to give them visual … Continue reading “My All 2020 Mathematics A to Z: Big-O and Little-O Notation”

My All 2020 Mathematics A to Z: Hilbert’s Problems


Beth, author of the popular inspiration blog I Didn’t Have My Glasses On …. proposed this topic. Hilbert’s problems are a famous set of questions. I couldn’t hope to summarize them all in an essay of reasonable length. I’d have trouble to do them justice in a short book. But there are still things to … Continue reading “My All 2020 Mathematics A to Z: Hilbert’s Problems”

Reading the Comics, January 20, 2014


I’m getting to wonder whether cartoonists really do think about mathematics only when schools are in session; there was a frightening lull in mathematics-themed comic strips this month and I was getting all ready to write about something meaningful like how Gaussian integration works instead. But they came around, possibly because the kids went back … Continue reading “Reading the Comics, January 20, 2014”

Reading the Comics, October 8, 2013


As promised, I’ve got a fresh round of mathematics-themed comic strips to discuss, something that’s rather fun to do because it offers such an easy answer to the question of what to write about today. Once you have the subject and a deadline the rest of the writing isn’t so very hard. So here’s some … Continue reading “Reading the Comics, October 8, 2013”

Fun With General Physics


I’m sure to let my interest in the Internet Archive version of Landau, Akhiezer, and Lifshiz General Physics wane soon enough. But for now I’m still digging around and finding stuff that delights me. For example, here, from the end of section 58 (Solids and Liquids): As the temperature decreases, the specific heat of a … Continue reading “Fun With General Physics”

General Physics from the Internet Archive


Mir Books is this company that puts out downloadable, translated copies of mostly Soviet mathematics and physics books. As often happens I started reading them kind of on a whim and kept following in the faith that someday I’d see a math text I just absolutely had to have. It hasn’t quite reached that, although … Continue reading “General Physics from the Internet Archive”
